How to click an specific TableRow within a TableLayout

Question

I made my own compound control that display a data grid using TableLayout and adding programmatically Tablerows within a loop depending of the Array of Object that im binding to it and now i want to select an specific row with its specific data in order to be used by a method. So how can i select an specific row retrieving its data to delegate a method?

hi you can try something like this,

 // create a new TableRow

    TableRow row = new TableRow(this);
    row.setClickable(true);  //allows you to select a specific row

    row.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            v.setBackgroundColor(Color.GRAY);
            System.out.println("Row clicked: " + v.getId());

           //get the data you need
           TableRow tablerow = (TableRow)v.getParent();
           TextView sample = (TextView) tablerow.getChildAt(2);
           String result=sample.getText().toString();
        }
    });

I tried Parth Doshi's answer and found it to be not quite correct. The view parameter in onClick is a TableRow, so when v.getParent() is called, it returns a TableLayout object, and so an exception is thrown when casting it to TableRow. As such the code that works for me is:

tableRow.setClickable(true);  //allows you to select a specific row

tableRow.setOnClickListener(new OnClickListener() {
      public void onClick(View view) {
        TableRow tablerow = (TableRow) view; 
        TextView sample = (TextView) tablerow.getChildAt(1);
        String result=sample.getText().toString();

        Toast toast = Toast.makeText(myActivity, result, Toast.LENGTH_LONG);
        toast.show();
    }
});
